| Abstract: | Based on lots of experimental study for liquid sodium Critical Heat Flux(CHF), and combined with the two phase flow thermal hydraulic characteristics and physical properties of liquid sodium, the following two phase flow patterns, thermal hydraulic characteristics such as incipient boiling flow,bubbly flow,plug flow,annular flow and two direction annular flow, are analyzed. From the experimental results, investigated the heat transfer crisis mechanism of the void explosion and liquid film destroyed or local dryout when liquid sodium occurs critical heat flux are also deeply. |
